^gu.i 



eleven in number ; fourth with from one to three, anterior to 

 middle; fifth with from five to nine; sixth with from six to eight 

 strong, more outwardly directed, tubercles. Sides Avith tubercles 

 subobsolete. Apical ventral segment with a median excavation, sub- 

 divided into two deeper, suboval, longitudinal depressions, by a 

 somewhat raised median ridge, fringed at extreme apex with dense 

 hirsute setae; with a small tubercle on each side of the excavation 

 near apex, slightly projecting over excavation. Anterior femora 

 with a short ridge on the lower surface. 



<? In appearance and sculpture very similar to male ; slightly 

 more ovate; beneath convex, fifth segment with a /\ shaped impres- 

 sion, enclosing a somewhat raised, rather closely punctured area. 



Dimensions. — <? 17.5 x 7; ? 17 x 7 mm. 



Hah. — Victoria, Portland (J. E. Dixon). 



Of this fine species I have before me a series of 60 specimens, all 

 sent by Mr. J. E. Dixon. This long series has enabled me to take 

 into consideration questions of variation in size and tul^erculation. 

 In regard to size there is not an extreme range, the smallest male 

 measures 15 x 6 mm., and the largest female 18 x 8 mm. 



I have given the general range of the number of tubercles on each 

 interstice in the description, but as a rule the highest and lowest 

 numbers are exceptional. In regard to the second interstice, occa- 

 sionally five tubercles may occur, while in one specimen there are 

 none on that interstice. In the type <?, on the .second interstice 

 immediately above the apex, occurs a short tubercle or spine; this is 

 as a rule absent, being present in only 12 out of 60 specimens, and 

 in 6 of these it occurs on one side only. It is not a sexuail 

 character, though the tubercles seem to occur rather oftener in the 

 male. 



Of previously described species, the present one is most closely 

 allied to T. tuherculaUis, Macl. The apical excavation is similar 

 in type in the two species; in T. tuherculatus, however, it is wider, 

 and the secondary depressions are farther apart, and not so deep. 

 Apart from the anal excavation, however, T. hystrix differs from 

 T. tuherculatus in its relatively short, more robust form, and in the 

 complete absence of the variegate clothing so characteristic of T. 

 tuherculatus. 



Talaurinus Leai n. .sp. 



<? Large; elongate, subparallel. Black, without clothing above, 

 a narrow line of silaceous scales on each side of median line and 

 marginal plate of rostrum. Setae black.
